Shades of certain complaints leveled at UNIX in the '80s. I do note that Linux doesn't seem to be getting better quite as fast as UNIX did.
Re: ChromeOS. You can do more on it than merely Google Docs. Scratch Jr. runs on it which I would love to use with my kindergarten kids. For very good reasons the school district has chosen not to pour money into Chromebooks, preferring to get full-function laptops, and unfortunately Scratch Jr. doesn't run on anything but ChromeOS, Android or iOS. Tablets could be great, but they're expensive and a management nightmare.

Yes, agreed - I liked the wet paint analogue very much.
But I do not see it as "kinds having no discipline" - it's rather a
different approach taken to the development process to help with scaling
of development.
In a small and controlled team you can force the focus on some spewcific
features and polish these features until they are done. But you can not
scale that model out to lots of developers and lots of features - at
least not with developer doingit for their own fun.
To scale the scope with enthusiast developers, you can do most of the
feature development easily but yoiu have to leave the tail of quality
control to someone more motivated. Linux has selected the model of
bleeding edge and fast developing upstream kernel that is released when
it seems good enough to thew developers, and then distribution makers
try to scale out the testing and stabilization. Some have busoiness
models that can put more reources into it, some use more crowdsourcing
for testing, bus ocassionally thre "wet paint" gets though (Ijust saw it
with container memory management reclaiming problem).

Meanwhile in the real world...

2.5 billion Android -- i.e. Linux users -- as of a year ago.
Now, approximately half the human race owns or uses Linux.
Meanwhile, in laptops etc.

gures
ChromeOS is the #2 most widely-used PC OS in the world, after Windows.
Only about 8 million units, if Q1 was 2M, but still.
Linux may not be particularly good in any single way, but its licence
and its cost outweigh technical elegance. I'm afraid that's the
reality.

Although, as the article starts to say, all these Chromebooks are
dumped into K-12 schools as throw away "starter" computers. They give
them access to Google docs, and do nothing else. Almost anything else
my kids do in school is on a Mac or iPad.

Most Linux code is written by professionals, not enthusiasts. Intel, Red
Hat, Samsung, IBM, all have large, full-time teams working on the Linux
kernel.
Solaris was also written by an extremely large team, reflecting diverse
interests inside Sun. Perhaps obviously, Sun Microelectronics,
SunSoft, and the compilers team all had slightly different needs from
the "Solaris" project.
There's no "magic bullet." Large teams are hard to organize. Interests
never align perfectly.

Message-ID: <201612171600.uBHG0gWN004249 at tiamat.an.bradford.ma.us>
now that my memory is prodded, i have a little sunos kernel tuner shell
script i wrote according to an old sun performance overview article.
sunos came out when memory was expensive and most machines had what
we'd consider really tiny amounts of ram; only really bulky machines
like db servers et al had anything like what we'd consider normal now.
the sunos kernel was optimized for memory in the single-digits of MB.
the script calculates and resets several variables in either kmem,
vmunix, or both. it can be run on a running machine. i don't know if
you'll get a perceptible, or even measurable, speedup.
i also have a ksh function which assists in calculating disk partition
tables for the cylinder-boundary metaphor, still needed as late as s8
but really obsolete in the zbr era. have late-model solarii given up
on it yet?
anyone interested in them?
